I can't think of many scenarios that would give you that impression. Did google personally reject you for being a man?
I haven't seen any effort to attract male talent. Of course having more women on the team will probably make a company more attractive to men, but I doubt that is the only thing they should bank on to attract men.
Just kidding - I didn't write a paper about it, nor did I conduct a rigorous study. Most of the Google Ads I have seen came via various Google Twitter accounts, like https://twitter.com/lifeatgoogle (Life at Google seems to be dedicated to hiring people for Google).
So my filter bubble might be to blame. I haven't seen the video you mentioned which features a man.
(Edit: I just scrolled through the first several dozen tweets from "Life At Google - I think there is definitely a bias to only show female engineers there.... However, it is of course only one Google Twitter account dedicated to hiring, I don't know how many others exist. Maybe it was created explicitly to target women and minorities, but then maybe they should somehow say so).
As for "Girls Who Code" as PR - does it increase the popularity of these firms with male coders, too? My personal impression with Google is that they are not interested in hiring male coders anymore...
